First thing I'd check is for a shorted A/C compressor clutch. Find the wiring to the compressor, unplug the connector to the A/C clutch, and see if it fixes it. You may want to find an auto electric specialist or a Dodge/Chrysler specialist.If you want to find a specialist, here's a directory link for you: https://repairpal.com/directory?address=35760&car_brand_names=Dodge

Fuse #2 (10amp) in the Junction Block powers the Coil side of the A/C Clutch relay. Fuse #5 (20amp) in the Power distribution Center (PDC) under the hood powers the contact side of the A/C Clutch relay AND the contact side of the Starter Motor Relay. Superbob is correct in making sure your A/C Compressor Clutch coil is not shorted or drawing excessive current.
